WlNDOW-SASH TIGHTENER SPECIFICATION forming part of Letters Patent No. 683,438, dated October 1, 1901.

Application filed June 24,1901. Serial No- 65,777. (NomodelJ To all whom it may concern.-

Be it known that I, OTTO OHILs, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in \VindoW-Sash Tighteners, of which the following is a specification.

The invention relates to improvements in window-sash tighteners; and it consists in the novel features and combinations of parts hereinafter described, and particularly pointed out in the claims.

, The invention comprises a novel device for attachment to a window-sash and having a movable part adapted to be wedged between the sash and its casing to bind the sash in position, whereby the sash will be prevented from rattling under the action of the wind blowing against the same. The rattling of window-sashes is frequently very annoying, especially at night, to nervous or ill persons; and it is the object of my invention to provide a simple and inexpensive device which may be attached to all ordinary window-sashes and utilized whenever desired for binding the sash within its casing, so that noises arising from the rattling of window-sashes may be absolutely prevented.

The invention will be fully understood from the detailed description hereinafter presented, reference being had to the accompanying drawings, in which Figure 1 is a front elevation of a portion of a window-casing and window-sash equipped with a tightener constructed in accordance with and embodying the invention, the parts of the tightener being illustrated in their normal inoperative position. Fig. 2 is a horizontal section of same on the dotted line 2 2 of Fig. 1, the sliding, portion ofthe attachment being by dotted lines illustrated in its operated position binding the sash within its casing, the movement of the sash due to the action of the tightener being indicated by dotted lines. Fig. 3 is a detached central longitudinal section through the sash-tightener on the dotted line 3 3 of Fig. 1. Fig. 4 is a detached vertical transverse section through the sash-tightener on the dotted line 1 4: of Fig. 1. Fig. 5 is a detached view of the metal blank from which the sliding portion of the sash-tightener is formed, and Fig. 6 is a View of the metal blank from which the stationary portion of the sash-tightener is formed.

In the drawings, 10 designates a portion of an ordinary form of window-sash, and 11 a portion of the window-casing for said sash, said casing being provided with the runway or groove 12 to receive and permit the usual vertical movement of the sash.

Upon the sash 10 is applied the sash-tightener made the subject of this application, said tightener comprising a stationary part or base 13 and a movable wedge part 14, said part 14 being held by the base 13 and adapted to have a sliding movement thereon.

The base 13 is formed from a metal blank (illustrated in Fig. 6) and is adapted tobe secured to the window-sash by means of screws 15 in the manner indicated in Fig. 1. The base 13 has at opposite sides the inwardlyturned lips 16 16 to form guides for the movable or wedge part 14, and at the inner end of said lips 16 are provided the small ears 17 17, which constitute stops to prevent the movable or wedge part 11 from losing its connection with the base 13. The base 18 at its end adjacent to the casin g 11 is provided with the cars 18 18 to receive the screws 15, by which the base may be secured to the window-sash 10, said ears 1S projecting beyond the plane of the movable or wedge part 14, so that the heads of the screws may not under any circumstances interfere with the movement of the latter.

The movable or wedge part 14 of the tightener is formed from the blank of sheet metal illustrated in Fig. 5 and comprises a basesection 19, adapted to the face of the base 13 and having at one end a lip 20, while at its other end, adjacent to the window-casing 11, said portion 19 is integral with the inclined section 21, which extends outward at an anthe section numbered 23, which curves under the section 2l, being formed into a series of springs 24 25. The end springs 24: are curved on continuous lines toward, Fig. 3, the base section 19 of the movable or wedge part 14:, while the end of the spring 25 is turned at rather an abrupt angle, as denoted at 26, to engage the said section 19 and afford a rather firm projecting portion under the inclined section 21 to aid in affording adequate resistance to said section 21 when the device is in use.

The parts of the tightener are illustrated in Fig. 1 in their normal inoperative position, and in said Fig. 1 it will be seen that a space is left between the end of the movable or wedge part 14 and the edge of the windowcasing 11. When it is desired to secure the sash against rattling, the attendant will by pressing on the thumb-piece 22 drive the outer end of the movable or wedge part 14 between the wind ow-sash and its casing in the manner indicated by dotted lines in Fig. 2, the said part 14 when thus moved between the sash and its casing operating as a spring-wedge to firmly bind the sash against its casing and prevent any rattling of the sash due to the action of the Wind or other cause. When it is desired to relieve the sash 10 from the action of the movable or wedge part 14, the attendant will by grasping the thumb-piece 22 withdraw the said part 14 from the position in which it is shown by dotted lines in Fig. 2 to the position in which it is shown by full lines in Figs. 1, 2, and 3, the part 14 being then free of the sash-casing 11 and performingno function. The movable or wedge part I 14 is prevented from losing its connection with the base-section 13 by reason of its construction and the engagement therewith of the guiding-lips 16. \Vhen the movable or wedge part 14 is moved in a direction toward the casing 11, the lip 20 on said part 14 may contact with the ears 17, formed on the base 13, said lip 20 constituting an effectual stop to prevent the separation of the part 14 from the base 13, and when the part 14 is moved in an opposite direction the guide-lips 16, being turned inward over the base-section 19, will serve as stops to prevent the escape of the part 14 from the base 13. The part 14 is of wedge-like form, and between the sections 19 21 thereof, which define the wedge outline, is disposed the springmember represented by the section 23, which under the compression due to driving the end of the said part 14 between the window-sash and its casing will exert an outward spring pressure or tension sufficient to bind the sash against its casing and prevent any jarring motion in said sash. The spring member represented by the section 23 also prevents the flattening down of the section 21 into a parallel line with the base-section 19, and hence under no ordinary circumstances will the part 14 while in use be deprived of its wedge-like form and spring action. The section 21 being of metal will of itself, when pressed toward the base-section 19, exert an outward spring tension.

During the sliding action of the part 14 the lower end of the spring 25 moves against the base 13 on a line between the lips 16 16, while the lower ends of the springs 24 move along the outer surface of said lips. The tightener thus comprises two parts, one being the base 13. and the other the spring-wedge part 14, the latter being carried by the base 13 and adapted to be manually moved thereon without losing its connection therewith. While I prefer the special form of spring member 23 illustrated, I do not confine the invention to any special construction of said member, since its form may be modified within the scope of my invention.

What I claim as my invention, and desire to secure by Letters Patent, is-

l. The window-sash tightener comprising the base 13 for attachment to the windowsash and having the guide-lips 16, and the movable or wedge part 14 mounted on said base between said lips and adapted to be pressed between said sash and its casing, said part 14 comprising the base-section 10 and inclined spring-section 21; substantially'as set forth.

2. The window-sash tightener comprising the base 13 for attachment to the windowsash, and the wedge part 14 mounted to slide on said base and adapted to be pressed between said sash and its casing, said part 14 comprising the base-section 19, inclined section 21 and spring member 23, the latter being interposed between said sections 19 and 21; substantially as set forth.

3. The window-sash tightener comprising the base 13 for attachment to the windowsash, and the wedge part 14 mounted to slide on said base and adapted to be pressed between said sash and its casing, said part 14 comprising the base-section 19, inclined section 21 and interposed spring member 23 having the springs 24, 25; substantially as set forth. a

4. The window-sash tightener comprising the base 13 for attachment to the windowsash and having the guide-lips 16 and cars 17, and the wedge part 14 mounted on said base between said lips and adapted to be pressed between said sash and its casing, said part 14 comprising the base-section 19 having the lip 20, the inclined section 21 having the thumb-piece 22, and the spring member disposed between said sections 19 and 21; substantially as set forth.
